http://www.sics.se/~adam/pt/ Protothreads are extremely lightweight stackless threads designed for severely memory constrained systems such as small embedded systems or sensor network nodes. Protothreads provide linear code execution for event-driven systems implemented in C. Protothreads can be used with or without an underlying operating system. Protothreads provide a blocking context on top of an event-driven system, without the overhead of per-thread stacks. The purpose of protothreads is to implement sequential flow of control without complex state machines or full multi-threading. Protothreads provide conditional blocking inside C functions. # No machine specific code - the protothreads library is pure C # Does not use error-prone functions such as longjmp() # Very small RAM overhead - only two bytes per protothread # Can be used with or without an OS # Provides blocking wait without full multi-threading or stack-switching # Freely available under a BSD-like open source license Might be interesting for us? -- Jeroen Ruigrok van der Werven <asmodai(at)wxs.nl> / asmodai / kita no mono Free Tibet! http://www.savetibet.org/ | http://ashemedai.deviantart.com/ http://www.tendra.org/ | http://www.in-nomine.org/ Hypocrisy is the homage which vice pays to virtue...
